Disasters are threatening and highly dynamic situations, marked by high levels of information need and low levels of information availability. Advances in communication technologies have given people more ways to seek information and communicate—a redundancy that can help people cope with disaster situations and support subsequent recovery. This article presents results from a longitudinal study of New Orleans musicians in the aftermath of Hurricane Katrina. The authors found that in the immediate aftermath, musicians used cell phones and the Internet to locate family and friends and obtain information unavailable in broadcast news reports. Seeking and redistributing information resulted in the creation or discovery of online spaces that became virtual instantiations of the physical environments from which the musicians were barred. For those who had to leave New Orleans, these online spaces helped them maintain connection with their local communities. As recovery continued, many musicians discontinued or adjusted their use of technologies that did not fit the cultural and social context of their everyday lives. Those who returned to New Orleans focused their energies on rebuilding, often eschewing mediated communication for New Orleans—style in-person interaction. Those who remained away found that digital connections to the New Orleans community were insufficient to maintain a sense of belonging.

This paper considers how emergency response organizations utilize available social media technologies to communicate with the public in emergencies and to potentially collect valuable information using the public as sources of information on the ground. The authors discuss the use of public social media tools from the emergency management professional’s viewpoint with a particular focus on the use of Twitter. Limited research has investigated Twitter usage in crisis situations from an organizational perspective. This paper contributes to the understanding of organizational innovation, risk communication, and technology adoption by emergency management. An in-depth longitudinal case study of Public Information Officers (PIO) of the Los Angeles Fire Department highlights the importance of the information evangelist within emergency management organizations and details the challenges those organizations face engaging with social media and Twitter. This article provides insights into practices and challenges of new media implementation for crisis and risk management organizations.

The Internet opens new options for communication and may change the extent to which people use older communication media. Changes in the way people communicate are important, because communication is the mechanism people use to develop and maintain social relationships, so valuable for their physical and mental health. This paper uses data from a national panel survey conducted in 2000 and 2001 to examine the influence of Internet use on communication and on social involvement. In doing so, it contrasts the conclusions one can draw from cross‐sectional and longitudinal data on these issues. Longitudinal analyses provide stronger evidence of the causal effects of using the Internet than do the cross‐sectional ones. The longitudinal data show that heavy use of the Internet is associated with reductions in the likelihood of visiting family or friends on a randomly selected day. Cross‐sectional analyses show high correlations between the frequency with which respondents communicate with specific family members by visits, phone calls and email, suggesting that communication in one medium stimulates the others. In contrast, longitudinal analyses suggest that the links between communication media are asymmetric: visits drive more email communication and phone calls drive more visits, but email drives neither phone calls nor visits.
